[U-Boot] [PATCH 32/34] imx: ventana: set HDMI video in to yuv422bt656 for GW551x-A

The initial revision of the GW551x does not connect enough signals between
the HDMI receiver and the IMX6 CSI for 16bit capture mode necessary for
yuv422smp capture. Future revisions will, but for the initial rev force it
to yuv422bt656 mode which requires an 8bit video data bus.
